[lttng-dev] Crash on 3.19.3 kernel

[lttng-dev] Crash on 3.19.3 kernel

[Sébastien Lorrain]

Hello LTTng folks,

I'am using Archlinux with stock 3.19.3 kernel and I'am experiencing a 
crash with the latest and greatest lttng.
I compiled lttng-tools without UST support.

$uname -a
Linux redwind 3.19.3-3-ARCH #1 SMP PREEMPT Wed Apr 8 14:10:00 CEST 2015 
x86_64 GNU/Linux

Here's the compile log of lttng-modules :
http://paste.ubuntu.com/10834007/

I noticed I'am missing  CONFIG_KALLSYMS_ALL, but I don't know if it is 
really relevant as lttng-modules 2.6 was running fine without it.

Here's the syslog/journal after a crash (on a test VM)
http://paste.ubuntu.com/10833873/

Any help in debugging that would be greatly appreciated!

Thanks!
Lrouge/
Sebastien Lorrain.

Hi S?bastien,

I can reproduce this as well. I suggest you file a bug
(http://bugs.lttng.org/projects/lttng-modules), so that the issue is
tracked and fixed before the next release.

It should be fixed now, can you confirm ?

Thanks,

After a quick test, it's certainly better than it was.

Thanks!

Seems to work for me too, no kernel panic and tests are running fine!

Thanks a lot!

Sebastien.
